They deliver deoxygenated blood from the liver and other lower digestive organs like the colon, small intestine, stomach, and pancreas, back to the heart; this is done via the IVC. Since the liver serves the important function of filtering blood as it moves from the digestive tract, these veins are particularly important for overall health. Excerpt Obstruction to the blood flow through the hepatic veins leads to a pathological-clinical entity known as Chiari's syndrome, of which there have been reported, as far as the authors could determine, no reports of Chiari's syndrome.
